Light and (soul) fire cannot be destroyed by ender dragons, but aren't in #dragon_immune

Pretty straightforward.
Light, fire and soul fire (latter two via #fire) are included in #dragon_transparent, a tag making blocks immune to the dragon, yet able to be flown through. Unintuitively, the #dragon_transparent tag is not in #dragon_immune, which prevents ender dragons from breaking blocks. As such, using #dragon_immune to find blocks the ender dragon cannot destroy falsely doesn't succeed for light and #fire. This is an issue for commands and data packs.

Suggested fix:

• Include #dragon_transparent as an entry in #dragon_immune
• Additionally, make #dragon_immune solely responsible for blocks not being destroyed, rather than both tags.
